# Atlassian — Style Reference
> Confetti-edged engineering blueprint. A clean white enterprise canvas interrupted by dark navy editorial panels framed in torn geometric color — vivid violet, taxicab yellow, electric blue, leaf green — like precise diagrams pinned between paint-splattered dividers.

Atlassian operates as an enterprise workshop dressed in casual confidence: a white canvas where dense product interfaces meet bold, colorful editorial moments. The visual system splits between quiet functional surfaces (white, light gray, subtle blue) and expressive dark hero blocks (near-black navies) framed by fragmented geometric confetti in vivid violet, yellow, blue, and green. Typography is a paired custom sans family — Charlie Text for dense UI, Charlie Display for editorial headlines that grow to 80px with tightened tracking. Components are large, rounded, and borderless — pills for actions, generous 20px radii for cards, almost no shadow. Color is disciplined: one electric blue drives every primary action and link, while chromatic energy lives only in decorative edges and section dividers, never bleeding into functional UI.
